Overall Satisfaction with DataStax

Use Cases and Deployment Scope

It is being used by a department to address the need to rapidly ingest data.

Pros and Cons

Pros

It is always up, very fault tolerant.
Tunable consistency, flexible in that regard.
Nice management tools.

Cons

Support for aggregation functions is still limited.

Return on Investment

Almost zero downtime, best for business continuity.
Easy to do maintenance online.

As an open source technology Cassandra can be readily used with or without any commercial support. DataStax provides value-added services and features, and in the end it is up to individual situations to strike a balance between the desirability of such support/service versus the associated cost.

Likelihood to Recommend

DataStax is best for simple data schema with high speed of writes. Data layout and modeling is centered around how it is going to be queried. It's not very appropriate for complex ad-hoc querying and analytics.
